Offshore wind power cylindrical foundation, lattice type ice-resistant device and wind generating set

Abstract

The invention discloses an offshore wind power cylindrical foundation, a lattice type ice-resistant device and a wind generating set, and belongs to the technical field of offshore wind power tower ice resistance. The lattice type ice-resistant device comprises a transverse plate and longitudinal plates, the longitudinal plates are evenly arranged on the transverse plate in the circumferential direction, a stiffened plate is arranged between every two adjacent longitudinal plates, and the longitudinal plates and the stiffened plates are symmetrically arranged up and down with respect to the transverse plate. The impact force of floating ice can be decomposed into supporting force perpendicular to a shell plate more effectively, so that the damage mode of the floating ice is changed from compressive damage to bending damage; the arrangement is flexible, the wave load can be reduced through lightening holes in the longitudinal plates, and the number of the longitudinal plates required by the ice-resistant cone and the geometric dimension of an ice-resistant cone can be calculated and analyzed; the ice-resistant device is arranged along the periphery of a main body structure to achieve the optimal effect; and the ice-resistant device is simple in structural form, light in weight and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of anti-icing technology for offshore wind power equipment, and in particular relates to an offshore wind power cylindrical foundation, a lattice type anti-icing device and a wind power generating set. Background technique [0002] With the requirements of energy transformation, wind power has become one of the fastest-growing green energy sources due to its technological maturity and low cost of electricity. Offshore wind power does not need to occupy land area because it is close to the power consumption center, so the development of offshore wind power has been supported by the government and developers in recent years. [0003] In the construction of offshore wind farms, in the sea areas of coastal provinces such as Liaoning, Hebei, and Tianjin, it is necessary to consider the impact of sea ice on the infrastructure due to climate reasons. Due to the large impact force of sea ice and the various modes of ice load...

Problems solved by technology

[0004] However, the current anti-ice cone design greatly increases the water plane, which will increase the ultimate load and fatigue load of wave action in the absence of ice floes, resulting in a larger engineering volume of the foundation column to resist wave loads; and , the existing anti-ice cone design slope curvature remains unchanged, and does not reduce the impact force of the ice floes most efficiently, and cannot guarantee that the failure modes of ice floes of different thicknesses are all bending failures
